Description

Technical Field

[0001] The present invention relates to the technical field of metallized film production, and in particular to a metallized film evaporation system, a production method and a metallized film. Background Art

[0002] Metallized film is a layer of metal film deposited on the surface of polyester film instead of metal foil as an electrode. Because the thickness of the metallized film layer is much smaller than that of the metal foil, the volume after winding is much smaller than that of the metal foil capacitor. The metallized film used to manufacture film capacitors is composed of an insulating dielectric film and a vapor-deposited metal layer. A layer of metal film is deposited on the surface of the insulating dielectric film through a vacuum evaporation process. Among them, the metal film is mainly composed of aluminum, zinc or zinc-aluminum alloy materials, and aluminum is the most commonly used material for metallized film.

[0003] The patent with announcement number CN109023252B removes the oxide film on the surface of the aluminum wire by pre-crushing and post-grinding, thereby shortening the melting time, ensuring the concentration of aluminum vapor during the evaporation process, and improving the uniformity and thickness of the evaporation layer on the film surface.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Embodiment 1:

[0031] In one embodiment, the grinding mechanism 22 includes a fixed cylinder 221 with both ends open, an inner sleeve 226 coaxially arranged in the fixed cylinder 221, and an outer sleeve 227 sleeved outside the inner sleeve 226, wherein multiple groups of grinding pieces are arranged in the inner sleeve 226, a storage area is formed between the inner sleeve 226 and the outer sleeve 227, and a storage area is provided on the inner sleeve 226 and between two adjacent groups of grinding pieces for the storage area to communicate with the cavity of the inner sleeve 226. The air outlet 2261 of the inner sleeve 226 is provided with an air suction component inside and at the feeding end. The two ends of the surface of the outer sleeve 227 are rotatably sleeved with an inflatable ring. The surface of the outer sleeve 227 is provided with a through hole 2271 connected with the inflatable ring. A filter component is provided between the inflatable ring and the air suction component. The air suction component sucks in the dust airflow generated by grinding, intercepts the dust through the filter component, and then sprays it to the surface of the aluminum wire through the air outlet to blow away the dust on the surface of the aluminum wire.

[0032] Specifically, refer to Figure 1 as well as Figure 2 The aluminum wire is located in an area surrounded by multiple groups of grinding pieces. When an external force drives the outer sleeve 227 to rotate, the outer sleeve 227 drives the grinding pieces to rotate on the surface of the aluminum wire through the inner sleeve 226 to grind and remove the oxide film layer on the surface of the aluminum wire. The air suction component sucks in the air flow containing dust and transports it to the filter component to intercept and filter the dust. The filtered air flow enters the two groups of inflatable rings, enters the storage area through the through hole 1 2271, and is finally sprayed onto the surface of the aluminum wire through the air outlet 2261. On the one hand, the air flow sprayed onto the surface of the aluminum wire can blow away the residual particles to make the surface of the aluminum wire cleaner. On the other hand, the blown gas can The surrounding dust is blown into the suction component, which can promote the dust to enter the suction component, increase the coverage area, prevent dust from flying around, and improve the dust removal effect. The suction component includes a collection cover 229 arranged inside the inner sleeve 226 and an exhaust frame 225 sleeved on the surface of the fixed cylinder 221. The collection cover 229 is connected to the exhaust frame 225 through a pipeline, and the exhaust frame 225 is connected to the filter component through a pipeline, and a fan and a one-way valve are provided on the pipeline.

[0033] In one embodiment, a driving member is further included, which includes a gear 1 222 fixedly sleeved on the surface of the outer sleeve 227 and a motor 224 fixedly installed on the outside of the fixed cylinder 221, and the output shaft of the motor 224 is fixedly sleeved with a gear 223 adapted to the gear 1 222, the motor 224 drives the gear 2 223 to rotate, and the gear 2 223 drives the gear 1 222 to rotate through meshing, wherein a notch is opened on the fixed cylinder 221 for the gear 2 223 to mesh with the gear 1 222.

[0034] In order to improve the grinding effect of the aluminum wire, the grinding piece includes a moving rod 2281 movably plugged into the inner sleeve 226, a grinding sheet 228 is fixedly connected to the bottom of the moving rod 2281, a spring 2282 is wound around the surface of the moving rod 2281 and is located between the inner sleeve 226 and the grinding sheet 228, and the grinding sheet 228 includes an inclined section and a straight section integrally formed with the inclined section, and the diameter of the insertion area surrounded by multiple groups of the inclined sections gradually decreases in the direction away from the feed end;

[0035] Specifically, refer to Figure 2 as well as Figure 4 The inclined sections on the multiple sets of grinding sheets 228 surround a conical area, which can provide a clear guide for the insertion of the aluminum wire, making it easier to insert the aluminum wire between the multiple sets of grinding sheets 228. The spring 1 2282 can make the multiple sets of grinding sheets 228 contact the moving aluminum wire, making it easier to continuously grind the surface of the aluminum wire, wherein the force conveying the aluminum wire is greater than the friction between the grinding sheet 228 and the aluminum wire, and the elastic force of the spring 1 2282 is greater than the centrifugal force generated when the grinding piece rotates.

[0036] In one embodiment, the filter assembly includes a filter box 2210, a mounting ring arranged in the filter box 2210, and a filter frame 2211 connected to the mounting ring, the filter frame 2211 divides the cavity of the filter box 2210 into cavity one and cavity two, the cavity two is connected to the suction assembly, the cavity one is connected to the inflation ring, the suction assembly transports the airflow containing dust to cavity two, the airflow entering cavity two intercepts the dust through the filter frame 2211, and the airflow after removing the dust enters cavity one and is transported by cavity one to two groups of inflation rings.

[0037] In order to avoid the problem of reduced filtration efficiency after the filter frame 2211 is blocked, a processing cylinder 2213 is provided on the top of the filter box 2210, and a piston 2217 is provided in the processing cylinder 2213. The bottom of the piston 2217 is fixedly connected to a movable rod 2219, and the bottom of the movable rod 2219 sequentially penetrates the processing cylinder 2213 and the filter box 2210 and extends to the interior of the cavity one. The end of the movable rod 2219 extending to the interior of the cavity one is fixedly connected to a connecting rod 2216 with a accommodating cavity, and the bottom of the connecting rod 2216 penetrates the mounting ring and extends to the outside of the mounting ring. The end of the connecting rod 2216 extending to the outside of the mounting ring is connected to a cleaning piece, and the cleaning piece is movably sleeved on the surface of the filter frame 2211. The surface of the movable rod 2219 is located inside the processing cylinder 2213 and a section is wound with a spring 2218. The cavity 2 is connected to the processing cylinder 2213 through an air guide pipe 2212.

[0038] Specifically, refer to Figure 3 When the surface of the filter frame 2211 is blocked, the gas pressure in the second cavity becomes larger and larger. Since the second cavity is connected with the processing cylinder 2213 through the air guide tube 2212, when the gas pressure is greater than the elastic force of the second spring 2218, the gas pushes the piston 2217 to move downward, and the piston 2217 drives the movable rod 2219 to move downward. The movable rod 2219 drives the cleaning piece to move downward through the connecting rod 2216 to clean the particulate impurities blocked on the surface of the filter frame 2211. After the surface of the filter frame 2211 is cleaned, the gas pressure in the second cavity gradually decreases. Under the action of the restorative elastic force of the second spring 2218, the piston 2217 is pushed to return to the initial position, so that the cleaning piece moves to the initial position for the next cleaning.

[0039] To improve the cleaning effect of filter frame 2211, refer to Figure 3 A water storage cylinder is fixedly sleeved on the outer circumferential surface of the treatment cylinder 2213, and a connecting pipe for connecting the treatment cylinder 2213 to the water storage cylinder is fixedly installed on the side wall of the treatment cylinder 2213, and a one-way valve is arranged on the connecting pipe, and a water outlet pipe 2214 is arranged at the bottom of the water storage cylinder, and a pressure valve is arranged on the water outlet pipe 2214, and a serpentine hose is arranged between the bottom of the water outlet pipe 2214 and the connecting rod 2216. When the piston 2217 continues to move downward until the connecting pipe is exposed, gas enters the water storage cylinder through the one-way valve, and pressurizes the water storage cylinder until the pressure inside the water storage cylinder is greater than the pressure of the pressure valve, so that the water flow inside the water storage cylinder flows into the hose through the water outlet pipe 2214, and is transported to the connecting rod 2216 through the hose, and is transported to the cleaning part by the connecting rod 2216 to clean the surface of the filter frame 2211, thereby improving the cleaning effect of the filter frame 2211.

[0040] In one embodiment, the cleaning component includes a fixed ring 2215 movably connected to the filter frame 2211, and the inner wall of the fixed ring 2215 is connected to provide multiple groups of nozzles 22152 and brush assemblies 22151. The multiple groups of brush assemblies 22151 are alternately distributed with the nozzles 22152. The brush assemblies 22151 can clean the surface of the filter frame 2211, and the water flow sprayed from the nozzles 22152 can clean the surface of the filter frame 2211.

[0041] In order to prevent humid gas from adhering to the surface of the aluminum wire, a drying tube is provided between the cavity 1 and the inflation ring. The drying tube is filled with drying particles. The gas leaving the cavity 1 first enters the drying tube, and the moisture in the gas is removed by the drying particles in the drying tube before entering the inflation ring.

[0042] Embodiment 2:

[0043] The production method of the metallized thin film evaporation system comprises the following steps:

[0044] The aluminum wire is conveyed between multiple groups of grinding pieces. When the outer sleeve 227 is driven to rotate by external force, the outer sleeve 227 drives the grinding piece to rotate on the surface of the aluminum wire through the inner sleeve 226 to grind and remove the oxide film layer on the surface of the aluminum wire. The air suction component sucks in the air flow containing dust and conveys it to the filter component to intercept and filter the dust. The filtered air flow enters the two groups of inflatable rings, enters the storage area through the through hole 1 2271, and finally sprays to the surface of the aluminum wire through the air outlet.

[0045] The polished aluminum wire is transported into the vapor deposition boat 39, and the aluminum wire is heated and melted, and then overflows onto the surface of the film in a vapor state, and forms a vapor deposition layer after being cooled.
